For those too scared to go under the knife or brave the needle, these new cosmetics promise extreme, quick results. Overplucked your unibrow? Now you can rub on new hair out of a tube. Worried about your double chin? Just wear an adhesive patch for a halfhour, and it flattens out your flap.

“Cosmeceuticals” like lip plumpers don’t work very long – but that’s the point. Just like you wash off your mascara, these instant procedures have you looking like you’ve had plastic surgery, but only for one night.

But be forewarned – just because some of the products don’t physically hurt, it doesn’t mean your wallet won’t feel

The whitner half, which is made with stain fighter hydrogen peroxide, can be used as spot treatment after drinking red wine or coffee; just 6-10 seconds on each dirty tooth should do the trick.

Verdict: Our teeth looked about the same color, but our breath was minty fresh and our lips were gorgeous and

glossy.

Hair U Wear’s Put on Pieces

Price: $229-$279

Going from a sultry brunette to a fun-loving blonde might be good for morale. But your tresses are sure to end up dried and fried.

As a hair-saving alternative, check out these human hair extensions that can be cut, colored and even permed.

Verdict: The pieces are easy to incorporate in messy ponytails and up-do’s, but if you’re going to leave your hair down, you might want to go with what you’ve got – they tend to slip out pretty easily.

Model Co’s More Brows

Price: $24

Overtweezed? No worries.

Instead of penciling in the bald spots in your eyebrows, try out Model Co’s tube of fake hair – a clickable applicator filled with tiny hairlike particles that you can paint right on to your face (they come out in a gluey stream). And, while the clear packaging gives it a slightly gross I-just-got-these-out-of-the-drain feel, the fibers dry evenly and naturally.

Verdict: The little faux follicles matched perfectly with our brows, were easy to apply and, unless we told, no one would ever know that we had gone a little tweezer happy the night before.

Freeze 24/7’s Anti-Wrinkle Cream

Price: $115

Unlike the injectables – Botox and synthetic fillers – Freeze’s technology releases a blend of natural and herbal topical muscle relaxers that promise to help instantly zap fine lines and wrinkles. And, the results are said to last for almost 24 hours. The plant extract also promises to smooth out acne scars and fix crows feet, droopy brows and laugh lines.

Verdict: A test drive felt like someone was holding our face taut, and the burning effect didn’t last long.

Mark’s Tattoo Lip Color

Price: $6

Paula Dorf’s Air Kiss

Price: $25 for 54 cards

Lip color that kisses off is a waste of time – and money.

Tattoo lip color, in an applicator reminiscent of Crayola markers, goes on and stays put.

Alternatively, Dorf’s Air Kiss is a single-application lip color. Just press the cards between your lips, kiss and pull it out.

Verdict: Mark’s marker stayed on even when we drank coffee and ate sushi – to take it off, we wiped our lips clean with makeup remover. And Dorf’s perfectly pocket-size lip color went on evenly and even made us feel really cute when we were kissing it on.

Revlon’s Perfect Pedicure

Price: $11

Sometimes there isn’t enough time for a pedicure. And, since there are very few beauty crimes worse than exposing gnarly, unkempt toes to the world, the Perfect Pedicure offers a solution- press on toenails.

The French manicured plastic toe-sized pieces glue neatly on to your existing nails and take about five seconds a nail to apply.

Verdict: From afar they look perfect and natural, but up close they’re unattractive and look fake.

Joey’s Double Chin Firming Treatment Patch

Price: $25

The greasy and pungent chin patch, made with ginko biloba extract and wheat germ extract, is supposed to help boost the production of natural collagen and firm up the saggy chin area. And, it also boldly promises to minimize fine lines and wrinkles in a half-hour.

Verdict: After 20 minutes (the recommended time is 15-30 minutes) we didn’t see a visible difference. But, that doesn’t mean we won’t give it another try – the idea that anything could help eliminate the dreaded double chin gets at least a double take.
